The 5AB spec, which is the standard for drum sticks and is positioned between 5A and 5B, has been revived in various finishes in the Rebound series. The inspiration for this project was the Larnell Lewis Signature Fire Grain model, which was released last year and received positive reviews.The specifications have been fine-tuned to reflect his requests and have been incorporated into this new regular model. The grip thickness is .580/approximately 14.7mm, which is between 5A (.565/approximately 14.4mm) and 5B (.595/approximately 15.1mm), and has been added to the American Hickory & Long, Active Grip, and Fire Grain lineups. The center of gravity is closer to the grip, and the weight at the tip is light, resulting in a light sound. The most durable HICKORY drumsticks in PROMARK history. These are the most durable hickory drumsticks in PROMARK history, thanks to an innovative process that forges the outside of the stick in a 3000°C flame. Only the highest quality, strong wood is used, carefully selected through advanced wood selection techniques.The hardening process gives the surface a hard, strong, and unique look, improving the grain and resolution, bringing out the core of the sound more clearly.It also reduces damage from scrapes, chips, and dents, extending the life of the entire stick.
